BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofMandevilla plant, botanically known as Mandevilla sanderi andhereinafter referred to by the name ‘Lannewhampshire’.

The new Mandevilla plant is a product of a planned breeding programconducted by the Inventor in Malause, France. The objective of thebreeding program is to create new freely branching Mandevilla plantswith numerous unique and attractive flowers.

The new Mandevilla plant originated from a cross-pollination conductedby the Inventor in Malause, France in July, 2016 of Mandevilla sanderi‘Lanarizona’, disclosed in U.S. Plant Pat. No. 23,672, as the female, orseed, parent with a proprietary selection of Mandevilla sanderiidentified as code number si 09-0266-034, not patented, as the male, orpollen, parent. The new Mandevilla plant was discovered and selected bythe Inventor as a single flowering plant from within the progeny of thestated cross-pollination in a controlled greenhouse environment inMalause, France in June, 2017.

Asexual reproduction of the new Mandevilla plant by stem cuttings in acontrolled greenhouse environment in Malause, France since August, 2019has shown that the unique features of this new Mandevilla plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Lannewhampshire’. Thesecharacteristics in combination distinguish ‘Lannewhampshire’ as a newand distinct Mandevilla plant:

-   -   1. Upright to broadly spreading and vining plant habit.    -   2. Moderately vigorous to vigorous growth habit.    -   3. Freely branching habit.    -   4. Relatively short and glossy dark green-colored leaves.    -   5. Early and freely flowering habit.    -   6. Large flowers with purplish pink and purplish red-colored        petals and purplish red-colored throats.

Plants of the new Mandevilla can be compared to plants of the femaleparent, ‘Lanarizona’. Plants of the new Mandevilla differ primarily fromplants of ‘Lanarizona’ in the following characteristics:

-   -   1. Plants of the new Mandevilla have smaller flowers than plants        of ‘Lanarizona’.    -   2. Flowers of plants of the new Mandevilla have purplish pink        and purplish red-colored petals whereas flowers of plants of        ‘Lanarizona’ have white-colored petals.

Plants of the new Mandevilla can be compared to plants of the maleparent selection. Plants of the new Mandevilla differ primarily fromplants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla have smaller leaves than plants        of the male parent selection.    -   2. Flowers of plants of the new Mandevilla have purplish pink        and purplish red-colored petals whereas flowers of plants of the        male parent selection have white-colored petals.

Plants of the new Mandevilla can also be compared to plants ofMandevilla hybrida ‘Sunpararosta’, disclosed in U.S. Plant Pat. No.23,213. In side-by-side comparisons, plants of the new Mandevilla differprimarily from plants ‘Sunpararosta’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vigorous than plants of        ‘Sunpararosta’.    -   2. Plants of the new Mandevilla have larger leaves than plants        of ‘Sunpararosta’.    -   3. Plants of the new Mandevilla have larger flowers than plants        of ‘Sunpararosta’.    -   4. Flowers of plants of the new Mandevilla have purplish pink        and purplish red-colored petals whereas flowers of plants of        ‘Sunpararosta’ have dark pink-colored petals.
